For this reason, Meguiar's recommends for best possible results, always use a paint cleaner after claying to insure the finish is clean both on top of the surface as well as below the surface.

有一件重要的事必须要牢牢记住，如果一辆车的烤漆表面已经有黏附的脏污，则表示它表面底下有缺损的机率是相当高的，例如已嵌入气孔的脏污，基於这个理由，为了达到最好的成果，美克拉建议你永远在跑完瓷土后使用漆面清洁剂，这样做可以确保烤漆的表面和表面底下都是乾净的

Methodshexamethyldisiloxane polymer film was obtained by plasma polymerization method on coverslips. oxygen (o2) plasma treatment was employed to modify the surfaces with different time so that a series of surface with different wettability were produced. l929 cell were cultured on these surfaces to observe the cell attachment rate and cell spreading in 6 and 12 hours.

The results show that the surface layer of the air-exposed ZrVFe getter is covered with H20, CO2 and hydrocarbons, both Zr and V exist in the oxidized state, and vanadium oxide starts to reduce at 200℃. The activation results in the enrichment of Zr on the getter surface and the formation of the metallic carbides. H2O, CO2 and hydrocarbons sequentially desorb from the surface with the increase of temperature. H2 is the main gas which desorbs above 200℃ and O2 is not discovered. ZrO2 is reduced to near-metallic or metallic state because O in ZrO2 leaves the getter surface through diffusing into getter bulk.

结果表明：暴露于过大气的吸气剂表面覆盖着H2O、CO2及碳氢化合物等，Zr和V主要以氧化态存在；在吸气剂加热激活过程中，V的氧化物在200℃开始还原；激活过程导致表面近金属态Zr的富集以及部分金属碳化物的生成；随着温度的升高，H2O、CO2及碳氢化合物逐渐从吸气剂表面脱附，在200℃以上，主要脱附气体为H2，整个激活过程未发现O2；ZrO2还原为近金属态或金属态，主要是由于ZrO2中的O通过向吸气剂内部扩散而离开吸气剂表面所致。

Between 4-9L exposures, C2H4 has a desorption channel at 155-180K. C2H4 desorption at 130K maybe results from BrCH2CH2Br absorbs in Br atom toward surfaces, after C-Br bond scission, because C2H4 has no opportunity to touch surfaces so it desorbs at low temperature. C2H4 desorption at 210K is likely to be desorption limited that, BrCH2CH2Br docomposes to C2H4, only to desorb at higher temperature. This C2H4 desorption channel maybe comes from defect site desorption.

曝露量在4-9L之间，C2H4在155至180K的范围内也有脱附的管道。130K的C2H4脱附可能是因为BrCH2CH2Br分子以Br原子朝向表面的方式吸附，在断了C-Br键后，C2H4分子没有机会接触到表面在低温就脱附了。210K的C2H4可能是脱附所决定的，亦即BrCH2CH2Br分解后在表面形成C2H4，随后温度升高至较高温才从表面脱附，此C2H4管道也许是来自缺陷位置上的脱附。
